WINFIELD S. BELLOWS, .OF STEELTON, PENNSYLVANIA.

MOTOR FOR BALING-PRESSES.

Application filed May 21, 1913.

T0 all wiz-0m t may concern Be ithnown that I, WINFIELD S. BELLows, acitizen of the United States, residing at Steelton, in the county ofDauphin and State of `Pennsylvania, have invented certain new and usefulImprovements in Motors for Ealing-Presses, of which the .following is aspecification.

VThe object of my invention is to provide a fluid pressure motor vforbaling presses of novel, simple and efficient construction, havingprovision whereby a plunger ,may .be operated by pressure-fluid andwhereby the pressure-fluid maybe controlled `by a novel arrangement ofvalves and operating devices therefor.

The invention consists in the novel construction and combinations ofparts hereinafter fully described and particularly claimed.

In Ithe ,accompanying drawings, illustrating my invention: Figure 1, isa side elevation of my improved hailing press. Fig. 2, is a frontelevation thereof, .partly in section. Fig. 3, is a vertical section, online 3-3 of Fig. 2. Fig. 4, is a section through one .of the outletvalves. Fig. 5, is a section through the inlet valve.

Referring to the drawings, the casing of the baler comprises side walls2 and 4, a rear wall 5, a bottom 6, a top 7 and a `door 8 closing thelower portion of the front of the casing. The paper or other material tobe baled is adapted to be compressed within ,this casing.

Mounted centrally upon the top 7 of the casing and secured thereto is averticallyarranged cylinder 9 adapted to receive pres` sure iiuid.Fitted to the inner wall of the cylinder 9 is a piston 10 provided witha downwardly-eXtending rod 11 which carries a head or plunger 12 on thelower end thereof. This plunger 12 is adapted to move vertically withinthe casing, when the piston 10 is raised and lowered to compress thematerial to be baled within the lower portion of the casing.

Communicating with the upper end of the cylinder 9 is ahorizontally-extending pipe 13, and communicating with the lower end ofthe cylinder 9 is a pipe 14 which also tends horizontally and parallelto the pipe 13. The outer ends of the pipes 13 and 14 communicate with avertical outlet or waste Specication of Letters Patent.

pipe 15, the lower end of which extends below the lower pipe 14 and maylead to any ,suitable point of waste discharge.

The horizontal pipes 13 and 14 are also connected by a vertical pipe 16which communicates therewith for the supply of the pressure fluid to thecylinder 9. The central portion of the vertical pipe 16 is interruptedby a valve 17 having three ports 18, 19 and 2 The port 18 communicateswith a pipe 2l which leads ,from a suitable source of pressure Huidsupply, and the ports 19 and 20 communicate with the upper and lowerportions, respectively, of the pipe 16. The valve 17 has a turning plug22 provided with a passageway 23 which may be turned to establishcommunication between the ports 18 vand 19 to direct the `pressure iiuidthrough the upper portion of the pipe 16 andthe pipe 13 to the top ofthe cylinder 9, and which may be turned to establish communicationbetween the ports 18 and 2O to direct the pressure fluid through thelower portion of the pipe 16 and the pipe 14 to the .bottom of thecylinder 9.

The upperand lower pipes 13 and 14 are interrupted by valves 24 and 25,respectively, between the pipes 15 and 16. These valves 24 and 25 areadapted to be operated to 4open and close the pipes 13 and 14 outwardlyothe pipe 16, kand each valve is provided with a `turning plug 26, havinga passageway 27 therein, as shown in Fig. 4.

The valves 17, 24 and 25 are operated by a common handle or lever 28which forms an 4,extension of one of the lower arms 29 of a lazy tongs30. The other lower arm 31 of the lazy tongs 30 is pivoted at 32 to abar 33 which is secured to the side 4 of the casing. The outer end ofone of the upper arms 34 of the lazy tongs 30 is pivoted, at 35, to anarm 36 which extends fixedly from the turning plug of the valve 17,whereby, when the handle 28 is raised, the arm 36 will be drawn down andthe valve 17 operated to direct the pressure fluid to the top of thecylinder 9, and when the handle 28 is lowered, the arm 36 will be raisedand the valve 17 operated to direct the pressure uid to the bottom ofthe cylinder 9.

Connected to one of the central pivots 37 of the lazy tongs 30 is theupper end of a link 38, the lower end of which is pivoted to one end oia lever 39 which is fulcrumed,

at 40, on a bracket 41 secured to the side 4 of the casing; andconnected to the lever 39 is the lower end of a rod 42 which eXtendsbetween and is pivoted to the outer ends of arms 43 and 44 which extendfrom the turning plugs of the valves 24 and 25, respectively. It willthus be seen that when the arm 28 is moved to operate the valve 17, thcrod 42 will be moved by its connections to the lazy tongs 30 to operatethe valves 24 and 25. The operating devices just described for thevalves are so related and timed that when the handle 2S is raised tooperate the valve 17 to direct the pressure fluid to the top of thecylinder 9, the valve 24 will be closed and the valve 25 will be opened,preventing the pressure fluid from flowing out through the pipe 13 tothe pipe 15 and permitting the waste or previously used pressure fluidto flow from the bottom of the cylinder' 9 through the pipes 14 and 15,while fresh pressure fluid enters the top of the cylinder 9 and forcesthe piston down; and the said devices are so related and timed that whenthe handle 28 is lowered to operate the valve 17 to direct pressurefluid to the bottom of the cylinder 9, the valve 25 will be closed andthe valve 24 will be opened, preventing the pressure fluid from flowingout through the pipe 14 to the pipe 15 and permitting the waste orpreviously used pressure fluid to flow from the top of the cylinder 9through the pipes 18 and 15, while fresh pressure fluid enters thebottom of the cylinder 9 and forces the piston 10 therein up. It will,therefore, be readily understood that by operating the handle 28, thepressure fluid supplied through the pipe 21 may be caused to force theplunger 12 up or down Within the casing, as desired. Any suitablepressure fluid, such as water or air, may be employed, and any suitablepump or other device maybe Copies of this patent may be obtained for vecents each, by addressing the employed to create the desired pressureWithin the supply pipe 21.

I claim:

1. The combination of a cylinder, a piston within the cylinder, an inletpipe having two branches, one branch being connected to one end of thecylinder and the other branch being connected to the other end of thecylinder, a single valve operative to admit pressure fluid to either ofsaid branches, each of said branches having an outlet pipe connectedthereto and an outlet valve for controlling the outlet pipe, operatingarms extending from said outlet valves, a bar connected to saidoperating arms, an operating arm extending from said single valve, and ahand operated lever operatively connected to said bar and the last namedarm.

2. The combination of a cylinder, a piston within the cylinder, an inletpipe having two branches, one branch being connected to one end of thecylinder and the other branch being connected to the other y end of thecylinder, a single valveoperative to admit pressure fluid to either ofsaid branches,leach of said branches having an outlet pipe connectedthereto and an outlet valve for controlling the outlet pipe, operatingarms extending from said outlet valves, a bar connected to saidoperating arms, an operating lever for said bar, an operating armextending from said single valve, and a lazy tongs including a handoperated lever operatively connected to the last named arm and the firstnamed lever.

In testimony whereof I aff1X my signature in presence of two witnesses.
